Heavy Ink Deposit Problem

Posted on Mon, 17 Jul 2006 at 1:50



I have a small 4 head manual Lawson press and I'm currently printing a 3-color graphic on 50/50 T-shirts. I'm experiencing a problem of a heavy ink deposit on just the far left side of the graphic on the second (yellow) and third color (black). I've raised the off contact a bit and I've switched out squeegees to a stiffer durometer, but the problem still exist. I've also trid to put in a small piece of foam near the left side, did little help. The rest of the graphic looks just fine, but a small portion of the graphic on the left side is depositing WAY too much ink and looks like crap. :cry:

Any suggestions?

I'm printing on 85 mesh screen (brand new screens)

The problem is your mesh count. 85 is a very low mesh and will deposit way too much ink making consistany a problem.

If the ink is dark, and the garment lighter in color than you should be using a 125-155 mesh count. Then use a 70 durometer squeegee with about 1/8 - 1/4 inch of off contact and you should be fine.

There are many articles to read about printing on my website if you would like to check it out CLICK HERE.

just read your post...I think you might have 2 issues here. I think being that you are printing manually, you might be putting undue pressure (as careful as you might think you are being) on one side of the print, a pretty common issue. The other is definitely your choice of mesh. My lowest mesh count is 180/48. You shouldn't have much of a problem getting good coverage as long as you are holding a minimum of 25 N/cm of tension, even with high opacity colors.

try 110 for UB
with 156-230 for the other colors depending on the coverage for the design.

we use 83 mesh counts for our puffs and some metalllics and crystalina... 8)
